"Project took a little longer than expected but the crews were working during the hottest weeks of the year. Met or exceeded expectations. The few issues with minor aesthetics were discussed with the crew and solutions they suggested worked out well and look good. Dennis was very knowledgeable and approachable. Could easily contact him via text to go over any issues. Overall good work. Would recommend to friends and family and definitely consider for any future home improvements"

"Excellent all around, quote, promptness, clean up. Payment included stump grinding, which the crew was unable to do 3 weeks ago. Gary has reassured me that it will be done and explained the situation to me. Rating will be an A+ and I will be even more pleased when stump is removed. I plan to use Accurate Tree and Landscaping Service again for trimming and maintenance."
